-You can generate this file using `certtool --generate-dh-params --bits
-2048`.  If not set `mod_gnutls` will use the included parameters.
+By default, `mod_gnutls` uses the DH parameters included with GnuTLS
+corresponding to the security level of the configured private keys if
+compiled with GnuTLS 3.5.6 or newer, and the ffdhe2048 DH group as
+defined in RFC 7919, Appendix A.1 otherwise.

+If you need to use different DH parameters, you can provide a PEM file
+containing them in PKCS \#3 encoding using this option. Please see the

+section of the GnuTLS documentation for a short discussion of the
+security implications.
